TIRE-REMOVING T001'.

Application led January 1B, 1923.

To all u1/wm t `may con/cern:

Be it known that I, CLINT B. SNIDER, a citizen of the United States ofAmerica, residing at Independence, in the county .of Montgomery andState of Kansas, have 1nVA vented certain new and useful Improve mentsin Tire-Removing Tools, of which the I following is a specification.

This invention relates to improve-ments in tire removing tools andparticularly to the i ype for removing a pneumatic tire from the wheelrim.

One of the objects of the invention 1s to provide a device especiallydesigned for removing a pneumatic tire from a wheel rim wherein thedevice, when placed in operative position on a wheel rim and tire, haspower applied thereto for forcibly disen' gaging the tire from the rimand overcoming such difficulties as the tire being rusted to the rim orotherwise improperly held thereon.

The invention further rovides improvements in the art, especial y overthe device shown and described in applicationfiled by C. B. Snider onNovember 14, 1922, Serial No. 600,919.

With the above and other objects in view as the nature of the inventionis better understood, the same consists of the novel form, combinationand arrangement of parts hereinafter more fully described, shown in theaccompanying drawing and claimed.

In the drawing, wherein like reference characters `designatecorresponding parts throughout the several views,

screws carried'by the outer end of the frame preventing sliding movementof the shiftable casing with the adjusting screw associated with thecasing and frame for positioning the same with respect to the tire, and

Figure 7 is a cross-sectional view taken on line VII-VII of Fig. 1showing the screw adjustment for the inner end of the shiftable casing.

Referring more in detail to the accompanying drawing, there isillustrated a tire removing tool including a frame composed of a bar 1carrying a perpendicular frame 2 at its forward end, and a similar frame3 at its rear end, the forward end of the bar 1 being further providedwith an elongated arm 4 while a reinforcing rib 5 is carrled by the barand arm. As shown more clearly in Fig. 1, diagonal braces 6 extendbetween the outer ends of the rectangular frame 3 and the barl 1 at eachside of said frame.

An elongated casing 7, rectangular in crosssection, has its oppositeends ypositioned in the rectangular frames 2 and 3,'the casing 7 beingtransversely slidable in the frames 2 and 3, and so constructed andmounted to be held against longitudinal movement. The inner end of thecasing 7 at each side thereof is pro-vided with a laterally directedshoulder 8, the rear sides of said shoulder engaging the forward edgesof the side walls of the frame 3 as shown in Fig. 2, while pins or setscrews 9 carried by the side walls of the forward frame 2 are disposedto be engaged by the forward end of the casing 7, as shown in Fig. 2,the casing being transversely shiftable and held against longitudinalmovement.

A tire engagin member is carried by the casing 7, and inc udes anelongated rod 10, rectan ular in cross-section, and carries upon t eforward end thereof an arcuate tire engaging foot 11. The rod 10 isslidable within the casin 7 and is prevented from rotation therein Ebythe cross-sectional conguration above described.

The operating means for shifting the tire engaging member includes athreaded rod 12 working in a threaded bore formed in the head 13 carriedby the inner end of the casing 7 as clearly shown in Figs. 2 and 4, theouter end of the operatin rod 12 being provided with a handle 14. Ilponrotation of the threaded rod 12, the inner end thereof engages theadjacent end of the rod 10 for longitudinally shifting the rodeandposition:4 ing the arotuate-foot 11 for engagement with a tire, theouter end of the arm 4 carried by the frame bein@r provided with a hook15 for engagement W1th a-rvheel rim for anchoring the frame on the rimwhen the 'tire enraging member is forcing the opposite side of a tirefrom engagement with the rim.

In positioning the tool on a Wheel rim and tire, the ihook 15 engagesthe lower side fiange of a Wheel rim, itbeing assumed that the rim andtire are horizontally disposed, the operating screw rod 12 being movedto itslirnit of movement, as shown in Figs. 1 and 2 With the tireengaging foot 11 of the rod 10 engaging` the upper side Vor bead of :itire. The easing 7 beinlg transversely slidable in the rectangularframes 2 and 3, the adjusting screv;7 16 extending through the outerWall of the frame 2 is first operated for engaging the outer end of thecasing 7 for shifting the casing and tire engaging member carriedthereby in a. direction toward the tire for properly positioning thei'oot 11, the adjusting screw 1G threaded through the outer end Wall otthe frame 3 being then operated for transversely shifting the other endof the casing 7 in the opposite direction,y causing the casing 7 tofulorum at its point of engagement with the adjusting screw 16 forholding the tire engaging foot 11 in a substantially rigid and bindingengagement with a tire orbead. Q perationof they screw rod 12 by thehandle 14 Willcause the rod 10 to be projected from the casing 7 andwith the'foot 11 engaging th tire, the latter will be readily removedfrom-a Wheel rim, and rs'ueh inconveniences f asthe. tire beingmistedfitoithe frim vvill be readily;.overcome-"and f-th'e tire :easilyaandiresent mventonfit isireverthele tofbe zin-L erstood that minorchanges may be made r therein :without: departing from,.-tfhef-y spiritand 'soopenofgthe invention as claimed.
